Abstract
An ink cartridge for an inkjet printer having a laminated wall. The laminated wall defines: an air inlet; a regulator channel having a first end communicating with the air inlet and a second end defining a bubble outlet; and a wetting system for maintaining liquid in the regulator channel so as to ensure that air entering a headspace of the cartridge first passes through said liquid. The regulator channel is dimensioned to control a Laplace pressure of air bubbles drawn from the bubble outlet as result of supplying ink to a printhead, and thereby regulates a hydrostatic pressure of the ink.
